IMIPROVEM ENT IN STEAM-PU M PS.

Specification forming part of Letters Patent No. 36,623, dated October 7, 13362.

To all whom it may concern.-

Be it known that I, HENRY O. SERGEANT, of the city and State of New York, have invented a new and Improved Mode of Constructing Steam-Pumps; and I do hereby declare that thefollowing is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in placing the crank-shaft between the heads of the steam and pump cylinders, just above or below the piston-rod, and revolving it by means of two cranks and side rods, and taking the power from the back end of either the steam or pump cylinder. By this combination I have a pump with crank, balance-wheel, plain the balance-wheel.

E E represents the piston-rod, passing through the steam-cylinder and into the pump cylinder.

F is the crosshead, attached to the end of piston-rod. This cross-head carries the connecting-rods G G, whichare also attached to the crank-pins shown at D D.

The operation is very plain, the'piston-rods of the two cylinders being connected as one. When steam is admitted to the engine and put in motion, the pump will also be in motion,
